Application filed November 17, 1904. Serial No` 233,113.

To (all 1.0700711/ it 71mg/ concern:

Be it known that I, AMANDUs M. HEMBERG, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Harvesters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to harvesters of a class which are adapted to be pushed by horses hitched thereto in the rear of the body of the harvester, and has for its object to improve the same in the several particulars hereinafter noted.

The invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims.

In the accompanying drawings, which illustrate my invention, like characters indicate like parts throughout the several views.

Figure 1 is a plan. View of the improved harvester. Fig. 2 is a vertical longitudinal section taken on the line rc2 502 of Fig. 1. Fig. 3 is a transverse vertical section taken on the line w3 .fc3 of Fig. 1, some parts being' left in full. Fig. 4 is an enlarged sectional View showing certain of the parts shown in Fig. 3, sectioned on the same line as in said Fig. 3. Fig. 5 is a detail in section on the line .fc5 x5 of Fig. 3. Fig. 6 is a transverse vertical section on the line m fr of Fig. 1. Fig. 7 is a horizontal section on the line o7 af of Fig. 6. Fig. S is a detail in section on the line ms of Fig. 6. Fig. 9 is a section taken approximately on the line af m9 of Fig. 1, some parts being left in full and some being broken away. Fig. 10 is a detail in section on the line afl m10 of Fig. 9, some parts being' broken away. Fig. 11 is a detail view, in front elevation, showing the parts immediately at the left of the line-mark fr x on Fig. 9; and Fig. 12 is a bottom plan View of a portion of the machine-platform, showing also portions of the platform raising and lowering device.

The machine illustrated is of the so-called low-down type, and nearly all the running parts of the machine are supported directly or indirectly on a long transversely-eXtended platform-frame 1, which at its ends has heavy guides 2, vin which trunnion-equipped raising and lowering bars 3 are mounted to slide vertically. heels 4 are loosely journaled on the trunnions of said bars 3.

A long and heavy reach bar or pole 5 is rigidly secured at its forward end to the rear central portion of the platform-frame 1. To the rear end of the reach or push bar 5 is swiveled a depending steering-bracket 6, to the lower portion of which is journaled a. pair of traction-wheels 7. The steering-bracket 6 is provided with oppositely-projecting arms 8, which are connected by chains 9 to the opposite ends of a lever 10, which is rigidly secured at its central portion to a steering-rod 11, which rod is journaled in the reach or push bar 5 and in a bracket 12, secured thereon, and is provided at its Lipper end with a hand-wheel 13, which is within convenient reach of the driver seated on a seat 14, supported from the rear portion of said push-bar 5. The traction-wheels 7 are preferably connected for common movements, and one thereof is provided with .a large bevel-gear l5, that meshes with a pinion 16, carried by a short vertical shaft 17, which is passed axially through the pivot of the steering-bracket 6 and is journaled in the hub portion thereof. At its upper end the shaft 17 carries a bevelgear 18, that meshes with a bevel-pinion 19, carried by the rear end of a long shaft 20. rlhe shaft 2O transmits motion from the traction-wheels 7 to the power-driven parts of the machine, and it overlies the reach or push bar 5, is journaled in bearings 21 and 22 thereon, and is provided at itsextreme forward end with a sprocket 23.

The draft-horses are adapted to be hitched to the swingletrees of a two-horse evener 24, the beam of which evener is pivotal] y attached to the push-bar 5 in front of the tractionwheels 7, as best shown in Figs. 1 and 2.

As means for raising and lowering the platform-frame 1 on its supporting-wheels 4 a long cable 25 is attached to beams 1 of the platform 1, preferably as shown at 25 in Fig. 12. This cable 25 is extended longitudinally of the platform 1 in opposite directions, is passed over guide-sheaves 26, mount- IOO ed on the ends of said platform, and over guide-sheaves 27 on the upper ends of the bars 3, (see Figs. 3 and 5,) and from thence the cables are brought to the central portion of the platform and are passed over guidesheaves 28 and 29, as shown in Fig. 12. The ends of the cable 25 are brought along the pole or push-bar 5 to the rear portion thereof and are attached to windlasses 36, mounted on said pole and provided with the usual or any suitable means for locking the cable in any desired adjustment. As is evident, by winding up the cable on the right-hand side of the pole the right-hand side of the machine will be raised, while by winding the cable on the windlass on the left-hand side of the pole the left-hand side of the machine will be raised. Hence by manipulation of the two windlasses the platform 1 will be raised and lowered at will.

The sickle 31, which is of the usual construction and is mounted in the usual way on the finger-bar 32 of the machine, is connected by a pitman 33 to a crank-disk 34, which is carried by the forwardly-projecting end of a Vroller-shaft 35, which is mounted on the sides of the platform-'frame and is provided at its rear end with a sprocket 36. For a purpose which will presently appear the crank-disk 34 is provided with bevel-gear teeth 34". The roller-shaft carries a roller 352 At the left-hand end of the platform l is an idle roller 37, and approximately in horizontal plane therewith a short distance at the left of the roller 35 is an idle guide-roller 38. An imperforate deck 39, which is secured to the sides of the platform-frame, extends horizontally from the upper portion of the roller 37 to a point above the roller 38 and then inclines upward tangentially in line with the upper portion of the roller 35a. An endless Slat-andbelt conveyor 40 runs over the deck 39, over the rollers 37 and 35, and under the roller 38. On the front and rear frame-boards l" of the platform 1 are inwardly-projeeting guidecleats 41, that overlie the upper portions of the edges of the conveyer 40 and hold the same down onto the deck 39, as shown -in F ig. 3.

In Figs. 1, 3, 4, 7, and 8 parts of the binder are illustrated, and of the parts illustrated it is only desirable to note the knetter-shaft 42, which carries a discharge-arm 43, and the needle-shaft 44, which carries a needle 45, both of which shafts are suitably journaled in the side 1" of the platform-frame. A connecting-rod 46 connects an arm 42 of the shaft 42 to an arm 44L of the shaft 44. The needle-shaft 44 has rigidly secured stub-arms 44", in which is loosely journaled a rockshaft 47, which at its forward end has a vertically-projecting trip-arm 48 and at its rear end has a horizontally-projecting arm 49. T he numeral 50 indicates a binder-deck which is rigidly secured to the right-hand portion of the platform-frame and is slotted to pass the needle 45, trip-arm 48, and various other parts.

Journaled in the sides 1 of the platformframe is a crank-shaft 51, which, as shown, has two cranks, to each of which is pivoted a packer 52 in the form of a straight bar. The upper ends of the packers 52 reciprocate freely in eyes formed in keepers 53, which are pivoted on the transverse rod 54, supported by the said sides 1l of the platformframe.

The knetter-shaft 42 at its extreme outer end carries a fixed half-clutch 55, and the crank-shaft 51 near its outer end is provided with a half-clutch 56. On the knetter-shaft 42 inward of its half-clutch is a sprocket 57, which is loose, is adapted to slide, and is provided with a half-clutch 58, that coperates with the half-clutch 55. Loose on the crank-shaft 51 outward of the half-clutch 56 is a sliding' sprocket 59, which has a halfclutch 69, that cooperates with the half-clutch 56. The numeral 61 indicates a shipper-lever which is pivoted at 62 to the rear side of the plat'form-'frame 1 and at its upper end is formed with reverse projections 61, the ends of which are pronged and engage annular grooves 57 and 59a, respectively, in the hubs of the sprockets 57 and At its pivoted lower end the shipper-lever 61 is provided with an inwardly-projecting arm 63, that overlies the free end ofthe arm 49 of the rock-shaft 47. A spring 64, attached to the upper portion of the arm 61 and to the adjacent side 1" of the platform-frame, normally holds the half-clutch of the sprocket 59 interlocked with the half-clutch 56 of the crank-shaft 51 and holds the half-clutch 58 of the sprocket 57 out of engagement with the half-clutch 55 of the knetter-shaft 42. A sprocket-chain 65 runs over the sprocket 23 of the driving-shaft 20, under the sprocket 36 of the roller-shaft 35, over the sprockets 59 and 57, and under an idle guide-sprocket 66 on the rear portion of the platform-fram e, as best shown in Fig. 6.

The reel 67 is looselyjournaled in a pronged supporting-frame 68, which frame is rigidly secured to the forward end of a long adjusting-rod 69 and is provided with guide-rod projections 70. The guide-rod 69 works loosely through the upper portion of a guide 71, and the rods 70 work through bearing-guides 72,

` which guides are rigid on the rear portion of the platform-frame. The rod 69 extends rearward and terminates in a handpiece 73, which is within easy reach of the driver on the seat 14. The rear portion of said rod 69 is notched or serrated at 74 and is adapted to be locked to a perforated lock-bracket 75 by means of a pin or other form of latch 76. The teeth 74 permit the rod 69 to be locked in diliierent longitudinal adjustments, and the perforations in the bracket 75 permit said rod to be locked in different vertical adjustments. By this means the reel may be adjusted vertically and from front to rear of the machine.

As a means for driving the reel and for permitting its adjustments the mechanism best illustrated in Figs. 9 and IO is preferably employed. The right-hand end of the reel-shaft is provided with a miter-gear 77, that meshes with a miter-gear 78, through which gear 78 a square driving-shaft 79 is mounted to slide. An elbow-bracket 8O is journaled or loosely hung on a hub of the reel-supporting frame 68 and forms a bearing` for the hub of the gear 7S. The lower end of the shaft 79 is connected by a knuckle-joint 81 to a stubshaft 82, which is journaled in a suitable bearing 83 on the adjacent side plate l of the platform-frame. rIhe shaft S2 carries abevelpinion 84, that meshes with the bevel-gear 3a, before described.

Operation: The manner in which the machine may be raised and lowered and in which the reel may be adjusted has already been clearly described. It has also been made clear that all of the running parts of the machine are driven from the traction-wheels 7 through the long shaft 20, which overlies the reach or push pole 5. The endless slatand-belt conveyer 40 is continuously driven under the forward movement of the machine from the roller 35. The reel also is continuously driven under the forward movement of the machine. Normally the packers 52 will be driven, and the parts of the binder will remain stationary in the position indicated by full lines in Figs. 3 and 4L of the drawings. lVhen, however, the bundle on the binderdeck 50 has accumulated to the desired full size, the packers 52 acting thereon will force the same against the trip-arm 4:8 with sufficient force to raise the arm 49 and rock the shipper-lever 6l outward against the tension of the spring 64C. This outward movement of the shipper-lever 6l moves the two sprockets 57 and 59 outward, thereby uncoupling the crank-shaft 51 from the sprocket 59 and coupling the knetter-shaft 42 with the sprocket 57. The binder being' thrown into action will tie and discharge the bundle in the usual way. The discharge of the bundlereleases the pressure on the trip-arm a8 and permits the spring (Si, acting on the shipper-lever @Lto throw the knetter-shaft out of action and to again start the crank-shaft 51 and packers52 into action.

The machine described, while simple and of small cost, is thought to be efficient for the purposes had in view and to have many features of improvement over harvesters of standard construction.

It is thought by me that this machine will have very light draft and that there will be no side draft on the machine and that the machine may be very easily operated and controlled by the driver from the seat at the rear end of the reach or push pole.

It will of course be understood thatvthe machine described is capable of considerable modification within the scope of my invention as herein set forth and claimed.
